In this project we will address the behaviour of many-body systems embedded in (optical and microwave) cavities. Investigations will focus in particular on strongly correlated and quantum ordered 2D systems. The presence of a cavity enables reaching the ultra-strong limit of light-matter interaction, which can in turn lead to the emergence of novel quantum phases of matter. The field has recently emerged as a hot topic, with more and more papers (in particular experimental ones) being published on the control of quantum phases realised in van der Waals materials. Intriguingly, the form acquired by such phases can depend on the gauge chosen for the electromagnetic radiation. This fact has been recently studied for model systems such as ensembles of dipoles or continuous (jellium) models. However, no attempt has been made at investigating this physics in realistic models of materials, which will be the focus of this project.

在这个项目中，我们将解决嵌入（光学和微波）腔中的多体系统的行为。研究将特别关注强相关和量子有序的二维系统。空腔的存在能够达到光与物质相互作用的超强极限，这反过来又会导致新的物质量子相的出现。该领域最近成为一个热门话题，越来越多的论文（特别是实验论文）发表在范德华材料中实现的量子相控制。有趣的是，这些阶段获得的形式可能取决于为电磁辐射选择的规格。最近已经针对模型系统（例如偶极子系综或连续（jellium）模型）研究了这一事实。然而，尚未尝试在真实的材料模型中研究这种物理现象，而这将是该项目的重点。
